Benefits of technology

The patent text describes a method for identifying the cognitive capabilities of network devices. This helps to clearly distinguish between devices and avoids the risk of selecting a device with unknown cognitive capabilities for a network task. The method allows for the selection of a device that meet the task conditions based on the cognitive capabilities of different devices. This objective results in better network performance and improved network efficiency.

Problems solved by technology

Research shows that a large number of currently fixed-allocated spectra are not fully utilized, resulting in huge waste of spectral resources.
Because these devices are different in cognitive capabilities, when they are used to implement a task or function on a network, these cognitive capability differences bring differences in the specific implementation of the task or function, resulting in certain risks in the process of implementing a network task by network devices, and leading to failure to execute the network task.

embodiment 1

[0040]FIG. 1 is a flowchart of a method for implementing network cognition according to a first embodiment of the present invention, including:

[0041]Step S11: Determine a type of a received network task.

[0042]Determine whether the network task currently required to be completed is a sensing task, decision task, or reconfiguration task, or is a combination of any two of the three task types, or includes all of the three task types.

[0043]Step S12: According to the type of the received network task, select at least one cognitive capability identifier corresponding to the type of the network task, where the cognitive capability identifier is configured to identify a cognitive capability of a network device.

[0044]Identify the cognitive capability of each network device. The cognitive capability of each of terminals, access devices, and network devices may be represented by a parameter or an information element. Different cognitive identifiers are used to represent different cognitive cap...

embodiment 2

[0051]In a method for implementing network cognition disclosed in the second embodiment, a case in which a network task is a sensing task is taken for example for describing the process of the method, and its procedure is as shown in FIG. 2, including:

[0052]Step S21: Determine a type of a received network task.

[0053]The result of determination is the sensing task.

[0054]Step S22: According to the type of the received network task, select at least one cognitive capability identifier corresponding to the type of the network task, where the cognitive capability identifier is configured to identify a cognitive capability of a network device.

[0055]The network device identifier selected in this step can indicate a certain cognitive capability and level possessed by the network device, and its schematic diagram is as shown in FIG. 3. A solid circle indicates that the device has the cognitive capability of this item, and an empty circle indicates that the device does not have the cognitive c...

embodiment 3

[0067]In this embodiment, a case that a network task is a sensing task is still taken for example to further describe the method. Its procedure is as shown in FIG. 4, including:

[0068]Step S41: Determine that a type of a received network task is the sensing task.

[0069]The network task in this embodiment is still the sensing task, that is, a task for identifying the surrounding radio environment and then sensing whether an idle and available spectrum exist.

[0070]Step S42: Select two cognitive capability identifiers corresponding to the type of the network task, where the cognitive capability identifiers are configured to identify cognitive capabilities of a network device.

[0071]The cognitive capability identifiers selected in this embodiment include: an identifier indicating that the network device possesses a certain cognitive capability and level, and an identifier indicating cognitive capability parameter value possessed by the network device.

[0072]Among the cognitive capability id...

Abstract

The present invention discloses a method and an apparatus for implementing network cognition. The method includes: determining a type of a received network task; according to the type of the received network task, selecting at least one cognitive capability identifier corresponding to the type of the network task; using network devices with the at least one cognitive capability identifier as alternative network devices; determining an alternative network device that is among the alternative network devices and has a cognitive capability that meets a condition for performing the network task is a target network device; and controlling the target network device to perform the network task.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Application No. PCT / CN2011 / 073208, filed on Apr. 23, 2011, which claims priority to Chinese Patent Application No. 201010175706.3, filed on May 12, 2010, both of which are hereby incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates to the telecommunication field, and in particular, to a method and an apparatus for implementing network cognition.BACKGROUND OF THE INVENTION[0003]CR (Cognitive Radio, cognitive radio) is currently the most promising technology to settle the insufficiency of spectral resources. Research shows that a large number of currently fixed-allocated spectra are not fully utilized, resulting in huge waste of spectral resources. The cognitive radio can detect these idle frequency bands through cognition of the radio spectral environment, and dynamically access these frequency bands without interfering in a PU (Primary U...
